Answer #1

Please find the code below::

Gven code:

int cs = 340;
int *pointer = &cs;

//constant pointer is as below
int* const constPointer = &cs;

// a lvalue reference is as below
int& lvalueConst = *pointer;

// a rvalue reference - that is not possible

int&& *rvalueConst = *pointer; -> It will give compile time error because *pointer is lvaue and rvalue cannot be initiazed by lvalue.

The value of cs can be changed to 413 using the folllowing code.

*constPointer = 413;

Here the pointer is constant not the int , So value of cs can be changed.

    2) (10 pts) Write a function that takes in a pointer to a linked list of nodes storing integers and a variable named value, and returns the number of nodes in the list storing that value. For example, if a list pointed to by listPtr stores 2, 6, 2, 3, 4, 2, 6, and 6 and value = 6, your function should return 3, since 6 appears in the list 3 times. Please use the struct and function prototype provided...
